Cemented carbideyog cov hmoov metallurgical khoom tsim los ntawm carbide (wc, tic) micron-loj hmoov ntawm siab hardness refractory hlau nrog cobalt (co) los yog npib tsib xee (ni) thiab molybdenum (mo) raws li cov binder, sintered nyob rau hauv lub tshuab nqus tsev vacuum los yog hydrogen reduction furnace .
Thaum tsim khoomcemented carbid khoome, qhov loj ntawm cov khoom siv raw hmoov xaiv yog nruab nrab ntawm 1 thiab 2 microns, thiab purity siab heev.Cov ntaub ntawv raw yog dosed nyob rau hauv qhov kev faib ua feem, ntxiv rau cawv los yog lwm yam xov xwm nyob rau hauv ib tug ntub pob zeb, kom lawv tag nrho tov, crushed, qhuav, sieved thiab ntxiv rau ciab los yog cov pos hniav thiab lwm yam molding agents, thiab ces qhuav. thiab sieved los ua ib tug sib tov.Tom qab ntawd, cov sib tov yog granulated, nias, thiab rhuab mus rau ze lub melting point ntawm cov hlau bonded (1300 ~ 1500 ℃), lub hardened theem thiab cov hlau bonded yuav tsim ib tug eutectic alloy.
Tom qab txias, cov theem hardened yog faib nyob rau hauv ib daim phiaj uas muaj cov hlau sib txuas, uas yog sib txuas rau ib leeg los tsim ib qho khoom tag nrho.Lub hardness ntawm cemented carbide nyob ntawm lub hardening theem cov ntsiab lus thiab grain loj, piv txwv li lub siab dua lub hardening theem cov ntsiab lus thiab lub finer lub grain loj, lub hardness ntau dua.Lub toughness ntawmcemented carbideyog txiav txim siab los ntawm kev sib txuas ntawm cov hlau, thiab qhov siab dua cov ntsiab lus ntawm cov hlau sib txuas, lub zog khoov ntau dua.
